Fair enough. However, we need some mechanism to redirect gcc into using
the "right" as and ld, which is not /usr/bin/{as,ld}. You already ruled
out --with-as earlier. This is particularly important for using "reverse
cross compilers" to alleviate the address space problem on 32bit. It
would help a lot if you could remember what those issues were.

It already is discouraged. gcc-VER-TRIPLET is marked M-A:foreign.
Therefore apt prefers the native package over the foreign one. sbuild
now configures APT::BarbarianArchitectures to fully forbid the foreign
native compiler. To be really strict, we could add a dependency on
"native-architecture" to the native toolchains. However, that bears a
risk of inducing temporary installability issues when it is uploaded.
